An efficient stereoselective total synthesis of (+)-Cephalosporolide D from commercially available and
inexpensive starting material, (±)-propylene epoxide, is described. The key steps involved in this synthesis are α-
aminoxylation catalyzed by L-proline, followed by in situ reduction using NaBH4 and Yamaguchi macrolactonization.
Keywords: (+)-Cephalosporolide D, L - Proline catalyzed reaction, (±)-Propylene epoxide, stereoselective synthesis, total
synthesis and Yamaguchi macrolactonization.
